The Thermo Scientific Orion Star A211 Desktop pH Meter is an easy-to-use, reliable laboratory meter with advanced features and functions. Optional reading modes and stability indicators provide flexibility and control for your measurements. All key data, including temperature, date and time, reading type, measurement stability, active calibration information, and electrode status icons, are displayed alongside your measurement results. The screen displays calibration and setting instructions in multiple local languages and can be updated with new languages through software.
The comprehensive keyboard, featuring specific menu function keys, dual-use scroll/shortcut keys, additional power and measurement keys, record/view keys, and a stirrer key, makes operation simple and allows for quick and easy navigation. All settings menus are located in one place, and can be accessed directly using individual shortcut keys, thereby enabling rapid retrieval, evaluation, and modification of measurement and instrument settings.
Measure pH value, mV, relative mV, ORP, and temperature.
Utilize the automatic buffer recognition feature with NIST or DIN buffer sets for up to 5-point pH calibration, with an option to manually input custom buffer values.
Calibration editing options support single-point corrections without the need for full recalibration.
A well-informed, easy-to-read backlit image display screen, along with clear screen display indicators, simplifies operation.
Obtain critical readings through the stability indicator and optional reading modes — automatic readings maintain stability, continuous readings with the hold option display reading changes, and timed readings record data at specific time intervals.
If using the stirrer probe (Part No. 096019) controlled by a meter to mix the solution, there is no need for a magnetic stir bar.
Data logging and date/time tagging can be performed for up to 2,000 measurement sets, along with optional sample and user IDs.
Calibration logs can store the 10 most recent calibration results.
The measuring instrument's non-volatile memory ensures that your data and settings are protected even in the event of power failure.
Orion Star Com software can transmit data to a computer via USB or RS232 connection.
Flexible power options, compatible with universal power adapters or optional AA batteries
IP54 rated housing provides dust and splash protection; wall mounting is available for limited desktop space.
The meter includes: CE, Tri-combined TUV, and FCC A-grade certification
